For the high frequency testing you probably need to put the generator in 50ohm output impedance(see the highZ on your screen at the channel) and on your scope side use a 50ohm termination. I think these are off on your devices and maybe you see an effect of reflections
You are (in my opinion) perfectly correct. Look at 30:24, where you can see a huge response to a pulse. Frequency of that pulse is set to 5MHz, which gives me the period of 200ns, which is 4 divs on the oscilloscope screen, which means oscilloscope is set to 50ns/div, right? If I look at that huge ringing, then I see something like 4 full reflections per div, which gives me about 12.5ns for signal to travel whole loop (twice the length - forward and backward), so the line has to have about 6.25ns of delay. Propagation velocity of RG-58 cable is somewhere around 0.66, which gives me the physical length of 1.24m, which is in my opinion the legth of that BNC to BNC cable. They are typically about 1m long.
That is quite a lot of functionality for that price. Shame about the problems with the connections as I tend to use waveform generators to playback bespoke electrical signals to test my data acquisition systems. I didn't notice any calibration function within the device menus, unless it is within the software. Thanks for the review, not sure it would drive me to replace my DG1022 yet though.
Hi, the DG1022z is my first function generator, still have it on the workbench. Great machine! I only need FG with higher bandwidths because they are useful to review the small oscilloscopes that are sent to me. Nowadays they're reaching the 200Mhz like the DPOH180H from FNIRSI,. Thanks for watching and commenting.
It is not logical to buy a device that only has signal generator features for such a high price. It is considered a better decision to buy a device that has both oscilloscope and signal generator features at this price.
Hi, I had the same idea you have when I bought my MSO2102A, this will solve all my problems. Just a few time after I ended up buying the Rigol DG1120 (upgradable to 60Mhz) and soon realized that I will need a function generator with more bandwidth and Owon at the time, generously sent for review the one I had before. Rigol is a brand that I have since I started in electronics and was a really proud moment when they decided to collaborate with the channel. For a hobbyist, you probably can get away with a oscilloscope with a function generator. The oscilloscope that I will review soon, also has a model with the function generator, but the one I have is just the normal one. Thanks for watching and commenting.
Hi, it does some high pitch fan, but is not too loud, I think the one you're listening in the recording is from my Rigol MSO2102... that on is really loud. Thanks for watching and commenting.
Thanks for the video. I'm a little disappointed, I expected your device to be newer. Mine is also from the first series, it has some shortcomings, and there were times when it didn't turn on properly, I had to restart it. Sometimes you can see "Dolphinfish" in the parameters, then you have to restart it.... I hope it's not a hardware problem.🤐 You can't load your own wave yet, I hope Rigol will solve it soon. I've already heard about the new Firmware, but it's still under testing. I haven't seen any evidence.🥲
Hi, you're reporting a lot of issues, thanks for sharing. Other than the issue with UltraStation I didn't felt major problems, at least for now. I hope I don't encounter issues while testing the equipment's I have here waiting. Thanks for watching and commenting.

What is the 32 Mpts/CH Memory Depth Upgrade Option ? Can you explain ?

Poor noisy fan
